Let S be the amount in a savings account.
Let m be the number of months.
General equation
S = 132 + 27m
Specific question
July is the 7th month of the year including both January and July.
S = 132 + 7*27
S = 132 + 189
S = 321
Reasonableness?
Good question. You could estimate an answer.
Start with 150 dollars and say that you add 25 a month.
7 * 25 = 175
S = 150 + 175 = 325 All of this was done in my head. Since the exact answer obtained using the formula is 321, I think that's pretty reasonable using my estimate is a guide.
Answer:
His equation is correct but his calculations are incorrect.
Step-by-step explanation:
180-40=140 so y=140
Hope this helps!
I think it would cost $120 dollars I'm not quite sure...
1. $2.78
2. If it’s 20% off you save 13.90 so 69.50- 13.90 is $55.60
